JJ LUDWIG HINGE Filed Feb. 10, 1956 Jon/V L up m//Q A TTORNEY Patented Apr. 18, 1939 UNITED STATES PATE NT OFFICE 8 Claims.

My invention relates to a new and useful improvement in a hinge adapted for attaching to a stationary body another body swingable relatively thereto, such as -a door or the like. The invention is particularly adapted for use in mounting doors on vehicle bodies and the like and has for its object the provision of a hinge which will be simple in structure, economical of manufacture, durable and highly eicient in use.

Another object of the invention is the provision of a hinge having a stationary part which is -attached to the stationary supporting structure and a swingable part which is attached to the stationary part, so arranged and constructed that the swingable part may be inverted as to position to be used either on a left handed hinge or a right handed hinge.

Another object of the invention is the provision of a hinge of this class whereby the door will be swingably mounted on a supporting structure and movable into tightly closing position in the opening over which it is hung.

Another object of thD invention is the provision of a hinge so constructed and arranged whereby a door or the like, when being swung outwardly to open position, will move bodily outwardly for a short distance before beginning its swinging movement on the arms.

Another object of the invention is the provision of a hinge so constructed and arranged that, when mounted in place, all parts will be concealed so that no obstructions or projections will be present on the outer surface.

Another object of the invention is the provision of a hinge so constructed and arranged that when mounted in position it will in no manner mar or interfere with the ornamental appearance of the body.

Another object of the invention is the provision of a hinge so constructed and arranged that it may be mounted on a body in a highly concealed position and thus facilitate the buing or polishing of the body after the hinge is mounted thereon.

that sql-leaks andgroans may be reduced to a minimum.

Another vobject o f the invention is the provision of a hinge having a stationary part provided with a swingable part pivotally connected to th-e stationary part by a pair of independently swingable parts.

Another object of the invention is the provision of a hinge having a swingable part which, when swung to open position, will swing on two pivots a portion .of its swing and on another set of pivots during the remainder of its swing.

Other objects will appear hereinafter.

The invention consists in the combination and varrangement of parts hereinafter described and claimed.

The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification, and in which,

Fig.. 1 is a longitudinal, transverse, sectional view of the invention showing it applied, taken on line I-I of Fig. 2.

Fig. 2 is a sectional View taken on line 2-2 of Fig. 1.

Fig. 3 is a sectional view taken on line 3-3 of Fig. 1.

Fig. 4 is a sectional view taken on line ll-4 of Fig. 2 illustrating` the swinging movement of the door.

In the drawing I have illustrated the invention` used with a stationary body 9, associated with which is the swingable body or door I0. In the body 9 there is formed a recess Il in which is positioned the U-shaped stationary supporting member I2 having the ends I3 of its legs angularly turned outwardly from each other and secured 'by screws I4 to the stationary body 9. Connected by the screws I5 to the end face I6 of the door or swingable body I is a swingable part I'I of the hinge which is in a general way U-shaped and through one of the legs I'I the screws .I are projected. The opposite leg I8 is shorter than the leg II and is provided with a pair o f knuckles I9. Projecting outwardly from these knuckles are arms 20, each of which terminates in .a knuckle and through which is directed the pintle 2 IY which also passes through an opening formed in the arm 22 carried by the pivoted member 23 through which the pintle 24 passes. This pintle 24 also passes through the oppositely disposed legs of the U-shaped member I2 so that the pivoted member 23 is pivotally mounted on the member I'2. A pintle 25 passes through the knuckles I9 and also through a knuckle formed in the arm 26 which projects outwardly from the member 21. This member is tubular and a pintle 28 projects therethrough and also through the oppositely disposed legs of the U-shaped supporting member I2. The members 21 and 23 are substantial duplicates of each other as are likewise the arms 22 and 26. It is thus seen that the swingable part of the hinge, that is the body I1, is pivotally connected to the arm 22 and is adapted to swing on the pivot 2| while the arm 22 also swings on the pintle 24 as a pivot. The body I1 is also connected pivotally to the arm 26 by means of the pintle 251 and the arm 26 is adapted to swing on the pintle 28 as a pivot.

As the door is swung from closed to open position in the initial swinging movement, the door will move outwardly substantially bodily with a very slight swinging, moving from the dotted line position shown in Fig. 4 to the full line position. In this movement the members 23 and 21. are swung on the pintles 24 and 28, respectively, the member 21 swinging slightly more than the member 23, and in this swinging movementthe pintle 2i will travel on the circle indicated by the dotted line 36 and the pintle 25 will travel on the circle 31. This movement will continue until the arm 2S approaches closely to the edge of the opening I I whereupon the member 21 will remain momentarily stationary so that the pintle 25 will provide a momentarily stationary pivot about which the door swings. As this movement continues, the arm 22 is carried farther around in a counterclockwise direction, thus swinging the body 23. Thus the body 23 continues to swing while the body 21 remains momentarily stationary. This movement will continue until the door approaches fully opened position, whereupon, while the swinging movement of the member 23 continues, the member 21 will be swung inwardly in the opposite direction. Thus, in the opening movement, the arm 26 will swing outwardly until the same lies substantially ush with the edge of the U shaped member I 2 where it will remain momentarily stationary for a portion of the swinging and the pintle passing therethrough willl form a momentarily stationary pivot. Further swinging will effect inward swinging of the arm 26. The arm 22 will be continued to be swung until it approaches closely to the edge of the U shaped supporting member I2. This movement is'indicated in dotted lines in Fig. 1 and the path of travel of the edge of the door is indicated by the dotted line 39 in Fig. 4. In Fig. 1 the hinge is illustrated in full lines in closed position and in dotted lines it is indicated in open position. It is this use-of the double swinging action that permits the swinging of the door as described and eiects the advantages enumerated herein.

By reversing the position of the hinge, the same may be used either for a right or left swinging hinge.

The swingable part I1 andthe stationary supporting member I2 which form the hinge sections are properly termed hinge butts and in some of the claims appended hereto, this descriptive term is used to designate these parts.

It is believed obvious that the various advantages sought are thus obtained and that I have provided an economical, durable hinge possessed of these advantages.

While I have illustrated and described the preferred form of construction, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.
